Science of Insulation

The Science Behind Mechanical Insulation

The Mechanical Insulators Labor Management and Cooperative Trust (LMCT) advocates for the advancement of the mechanical insulation industry, including industry education.

Mechanical insulation is often referred to as the “forgotten technology.” While it is difficult to see mechanical insulation in real time, you will see results of this technology in your return on investment. Adding mechanical insulation to your mechanical system will result in a drop in energy costs and greenhouse gas emissions, while lowering operating costs.


What is mechanical insulation?

Mechanical insulation is a form of thermal insulation. It has many applications, but is mostly used on boilers, HVAC systems and duct work.

The ultimate purpose of mechanical insulation is to reduce energy waste, improve longevity of mechanical systems and reduce greenhouse gas emissions.


How does mechanical insulation work?

Mechanical insulation works by slowing conductive heat flow. This means insulation will prevent heat from flowing away from a system or facility outfitted with insulation.

The National Institute of Building Sciences (NIBS) through the National Mechanical Insulation Committee (NMIC) has developed the Mechanical Insulation Design Guide (MIDG) to provide a comprehensive source of information on the performance, use, testing and standardization of mechanical insulation in buildings and industrial facilities.
